Blackened oil painting can be restored into original form by the action of :
- A Chlorine
- B \(\mathrm{BaO}_2\)
- C \(\mathrm{H}_2 \mathrm{O}_2\)
- D \(\mathrm{MnO}_2\)
Answer & Solution
Correct Answer
(C) \(\mathrm{H}_2 \mathrm{O}_2\)
Step-by-step Solution
Detailed explanation
Blackening of oil painting is due to \(\mathrm{PbS}\) which is oxidised by \(\mathrm{H}_2 \mathrm{O}_2\) to form white \(\mathrm{PbSO}_4\)…
